Detailed explanation-1: -Complete answer: If an organism has 20 chromosomes, then the number of chromosomes the daughter cells have after mitosis is 20 because when a cell divides by the process of mitosis it produces two clone daughter cells having the same number of chromosomes (20) as the parent cell has.

Detailed explanation-2: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-3: -Hence, answer is ‘10 chromosomes’.

Detailed explanation-4: -Meiosis is also called reduction division. This type of cell division is involved in formation of gametes. The number of chromosomes is reduced to half at the end of meiosis. So, a cell having 20 chromosomes will give rise to four daughter cells having 10 chromosomes after meiosis.

Detailed explanation-5: -If the chromosome number for an organism is 22 before mitosis, then the chromosome number of each daughter cell after mitosis has taken place will also be 22. This is because mitosis produces two daughter cells that are genetically identical in terms of chromosome number and the genetic content of the chromosomes.
